TO ALL WHOM IT MAY GONCERN:

Be it known that I, ADAM R'. REESE, of Phillipsburg, in the county of Warren, and State of New Jersey, have invented certain new and useful Improvements in Machinery for Turning Buckets, Kegs, or other similar articles from a solid block of wood, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings which make part of this specification, and in which- Figure 1 represents a view in elevation ofmy improved machine.

Figure 2, a view showing the mode of fastening the cutters in the cutter-stock.

Figures 3 and 4 represent sections through the block fig. 3 showingv the blocks cut through with a straight taper for buckets, Kto., and iig. 4 showing the block cut through with a double taper to form kcgs.

It is the object of my invention simultaneously to cut from asolid block a series of concentric hollow cones and to this end my improvement consists in combin-A or frusta of cones to form the sides of buckets or kegs, ing a mandrel revolving in a xed position on a vertical axis, and carrying the block to be cut, with a series of parallel cutters moving up and down in a frame at a slight angle to the mandrel, as hereinafter described.

In the accompanying drawings a mandrel, A, is shown as mounted in suitable bearings in a frame, I3, and rotated by a band encircling the pulley C, or in any other well-known and proper way. A faceplate and screw, D, secured upon themandrel, holds the block to be cut. The cutters E are arranged parallel to ca-eh other, and side by side in a sliding frame7 F, moving in guides G, and moved up and down by a lever, H, or in some other well-known way. To secure the cutters in their holder,`thcy are placed side by side, with blocksc between them, and cramped by a sct-screw, g, at the sides, and a wedge, 2', at the front. By this means the cutters an readily be removed and replaced. v Y

The operation of the machine is as follows: VA rapid rotation is given to thc block O, shown in red in fig. l.

The cutters are then steadily moved up against the block, into which they cut at an angle to the mandrel, as shown in fig. l, cutting out a series of concentrioconcs, as indicated in fig. 3. In practice, however, I' prefer to cut the block nearly through, and their to separate the cones by cutting the block transversely. '[hc form shown in iig. 3 answers bestl for vessels of a. uniform taper, such as'buckets, 82e. To cut vessels tapering both ways from the centre, such as white-lead kcgs for instance, I cut the block half way through at one angle, and then reverse itin the holder and cut the other way. It is obvious that the taper ofthe concs could be varied by changing the angle at which the cutters enter the block. It is also obvious that either the guide-frame or the cutterfframe may be rendered laterally adjustable to vary the distance of thc cutters from the mandifehnnd consequently the size of the cones to'be cut. l i

The bucketsa're intended to be made of green wood, andto have a bottom of seasoned wood inserted. The shrinking of the bucket will make it tight. The bucket might also be split after being cut, and a bottom inserted and hooped in the' usual way. In turning kegs, should the bulge of the inner one exceed the diameter of the kerf of the outer keg, the splitting of the outer onewould of' course bc necessary beforev the removal of the` inner one. Y

Previous to my invention the only way .of turning buckets, of which I have any knowledge, was either by a single straight cutter moving horizontally, and acting on a block rotating on a horizontal axis, or by a series' of parallel. curved cutters having a swinging horizontal-movement, and acting on a block carried by a horizontal axis. The former plan would'cut but one cone at a'time, the latter would cut a-series of concentric curves, but the curved knives are objectionable from their tendency to spring, and in both machines the chips would be apt. to clog the spaces between the cones, all of which objections are obviated by my invention.

What I claim as my invention, and desire to secure by Letters Patent, is

, The combination of the vertical mandrel, revolving in a fixed position, and carrying the block, with a series of parallel straight cutters moving in an inclined path, nearly vertical, at an angle to tlre block, for vthe purpose of simultaneously cutting a series of concentric frusta of cones from a solid block.

I also claim the combination of the mandrel with the cutters, and the guides, arranged and operating substantially as described.

e In testimony whereof I have hereunto subscribed my name.

ADAM R. REESE.
